BTW, I was always surprised nobody had converted the bytecode interpreter
into a via-C compiler by unwinding the C code the interpreter goes through
to execute a specific OCaml bytecode program. You could even use this with
something like Clang to get JIT compilation to native code. Not very
efficient but surely much faster than interpreted bytecode...
